LCD Keypad Shield for Arduino

Arduino LCD Keypad Shield

This is a 16x2 LCD and Keypad shield for Arduino Uno, Diecimila, Duemilanove, Freeduino boards, and other Uno sized compatible boards such as the Sparkfun Redboard.

Blue Backlight with white words

uses 4 Bit Arduino LCD Library

Left, Right, Up, Down and Select buttons

Screen contrast adjustment

Arduino Reset button

The board uses different pins to the Arduino example sketches, so to make the display work, use the following sequence of pins when starting the library:

LiquidCrystal lcd(8,9,4,5,6,7);

The buttons are connected to only one analog input pin through resistors to give a different voltage for each button, thus saving on input/output pins. Reading the buttons is easy and example code is shown below
